checkmytrip will be no help in telling you whether the e-ticket has been revalidated properly, but usually that doesn't matter because a date/time change won't cause too many problems at the airport to get sorted. Re-routes do.
This is not the experience I have had recently whereby both time and flight no. schedule changes by USAirways resulted in the need to have new e-tix issued. The same e-tix number was not re-validated but new ones were issued. This happened on 3 seperate occasions since the original ticketed.
On two occasions ICC told me that new tickets were not required only for me to call back the following day to be told they were in the queue to be re-ticketed.
